    Energy microgeneration system in on-board devices comprising a microgenerator (3) connected with an adaptation circuit (8) and this, in turn, with a hybrid energy storage system constituted by a primary cell (1) non-rechargeable and a secondary rechargeable cell (2), to obtain high energy density and high power. An intelligent energy management system (4) carries out the charging of the secondary cell (2) through the microgenerator (3) or the primary cell (1). The microgenerator (3) is an oscillating system formed by at least one piezoelectric sheet (14a, 14b) cantilevered, being embedded at one end (13a, 13b) and with a mass (15a, 15b) at the opposite end, such different movements in the boat cause an oscillatory movement in said piezoelectric sheet (14a, 14b) exciting it and generating an electric current.

    reduced size, so depending on the application sheets will be installed
    piezoelectric (14b) transverse (figure 7 (b)) to take advantage of said
    displacements
    -The magnitude of the oscillations depend on the type of boat, but usually
    predominant in the stern.
    It must be taken into account that the selection of a generator based on piezoelectric sheets (14a, 14b) is not arbitrary, since they are more difficult to acquire and build. However, they offer the advantage that they generate voltage peaks of the order of volts, not like the magnetic ones, which are in the order of hundreds of millivolts and it would be necessary to use a transformer to increase the voltage levels. In addition, it is necessary to highlight the low frequency of oscillation of the ship.
    The energy generated by the piezoelectric sheets (14a, 14b) is alternating current, high voltage and low current, so it cannot be used directly to power any device. That is why, as seen in Fig. 4, the system has a low-drop AC / DC rectifier (10) in conduction, seeking to reduce losses. In a particular embodiment, the rectifier (10) employs a complete Schottky diode bridge. Due to the low level of voltage generated, it is necessary to use low voltage Schottky diodes in conduction, and even use a transformer to raise the output voltage.
    As can be seen in Fig. 4, which shows in greater detail the adaptation circuit (8), said energy is also stored in a first capacitor (11) connected in parallel with the rectifier (10) and whose load is constantly monitored. When it is detected that the charge in said capacitor (11) reaches a certain level, a switched DC / DC converter (12) that charges the storage system is activated. In this way, the energy adaptation is carried out in the most efficient way possible.
